Answer: C. A brood chamber is made by bees, but comb foundations are built by humans.
Explanation:
The brood chamber is a natural part of the beehive where the bee workers made cells where these works lay eggs. Here, development of the larvae and pupae takes place. The cells of the brood chamber holds the pollen, nectar and honey which is used to feed to develop the larvae.
Comb foundations are the artificial creation made by humans is a place made from wax which forms the base of the honeycomb. It is used to give the support to the beehive.
The epidermis is a barrier to ultraviolet rays, blocking much of the cancer-causing radiation from reaching the nuclei of cells called keratinocytes.
<h3>
What is keratinocytes?</h3>
- Skin cells, also known as epidermal keratinocytes, are highly specialized epithelial cells created for a very specific purpose: separating the organism from its environment.
- Keratinocytes, which make up the majority of the epidermis, have a variety of functions that are crucial for skin restoration.
- They carry out the re-epithelialization process, in which keratinocytes move, multiply, and differentiate in order to reestablish the epidermal barrier.
- The majority of the epidermis's cells, known as keratinocytes, begin in the basal layer, manufacture keratin, and help to create the epidermal water barrier by producing and secreting lipids.
- A kind of stratified epithelium known as keratinized stratified squamous epithelium has many layers of squamous cells, or keratinocytes, with the superficial layer of cells being keratinized.
- The skin's epidermis is made up of this kind of epithelium.
